To @ZZ whom, t may concern:

Beit known that I, WALTER S. RocKwELL,

a resident of New York, in the county of New y an improved portable forge operated by atomized liquid fuel andrwhich will be extremelyA simple in construction, comparatively cheap to manufacture, and most effectual when in` use.

Vith this object in View the invention consists in certain novel features of const-ruction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figures l and 2 are views in vertical section, taken at right angles to each other; and Fig. 3 is a View in horizontal section on the line :c x of Fig. 1.

A represents a cylindrical tank or reservoir for hydrocarbon, the side walls of which project above the top l thereof and the base of said tank provided with an angle-iron or flanged ring 2, as shown.

My improved forge B is provided on its bottom with a circular flange 2a, disposed in the upper end of the upwardlyprojecting walls of the tank A, the top of said forge being arched and provided With eyebolts 3 to facilitate removing the same from the tank when desired. A pipe-coupling 4 is secured in the upper end of tank A and comprises a casing divided by a diagonal partition 5 into tWo chambers G and 7, which latter chamber communicates with the interior of the tank. An air-inlet pipe 8 lcommunicates with the chamber 7, and a vertical pipe 8a, of smaller diameter than Vthe chamber 7, is disposed therein, passes through the partition 5, and communicates with the chamber G, and said pipe 8fL extends down into the tank A and terminates near the bottom thereof, where it is provided with any approved strainer 10. An oil-outlet pipe 9 communicates with the chamber G, and said pipes 8 and 9 are bent at right angles and extend parallel outward, and short pipes 13 connect the outer ends of said pipes 8 and 9 with a common outlet spout or atomizer 1st, having a valve 1G to regulate the flow therethrough. The pipes 13 are provided with valves 11 and l2, respectively, to regulate the passage therethrough to the atomizer or spout 14, which is also adapted to serve as a burner to direct the flame into the forge B through an opening 17 in one end thereof, and said forge is provided with an inner coating of fire-clay 1S and with a transverse bridge-wall 19 nearits forward open end, over which the llame is compelled to pass to distribute the heat throughout the entire interior of the forge, and an inlet-opening 2O for rivets or other articles to be heated is provided in the side wall of the forge just back of the bridge-wall, which opening also serves as an outlet for the burned gases and other products of combustion.

All air-inlet pipe 21 extends transversely beneath the forge and is adapted at one end for the attachment of any approved air-supply and is connected between its ends to the pipe S b v a pipe 22, which latter is provided between its ends with any approved air-regulator C to regulate the pressure of air passing therethrough. The other end of pipe 21 is bent upward and communicates with a horizontally disposed perforated pipe 23, mounted in a plane just below the opening 2O in the side wall of the forge, so as to deflect the burned gases and other products of combustion escaping through said opening up behind a screen or shield 24:, secured to the forge by arms 24a, and hence protect the operator from the4 injurious eeets of such gases and products of combustion. The pipe 21 is provided near pipe 23 with a suitable valve 25 to regulate the pressure of air fed to said pipe 23. An oil-inlet pipe 26 communicates with pipe 9, is normally closed by a'cap 27', and is pro vided between its ends with a cheek-valve 2S to prevent oil from escaping therethrough.

Suitable handles 29 are provided on the tank or reservoir A to facilitate moving the same, and a petcock 30 is provided in tank A, near the top thereof, to permit the air to IOO escape when the tank is being filled, and which also serves as an overflow to indicate when the tank is lled suiiieiently. At all points Where the pipes pass through the .walls of the tank they are secured against movement by jam-nuts, as shown.

The operation of my improvements is as follows: When it is desired to iill the tank, it

is simply necessary to attach an oil-supply pipe to oil-inlet pipe 26 and pump or other- Wise force the oil therein, which will `iiow past check-valve 2S into pipe 8 and from thence down through pipe 8a into tank A, the petcock 30 being previously opened to permit the air in the tank to escape, and as soon as a sufficient amount of oil is in the tank the petcoek will be closed and the oilsupply pipe removed and cap 27 secured onto theinlet-pipe 26 to protect the same. In operation air is forced into pipe 21 and through the air-regulator C into pipe S,where it iiows in both directions, as indicated by the arrows, one part of the volume of air passing to the valve 1l and the other part of the air passing through the chamber 7' into the upper portion of the tank or reservoir A to force oil up through pipe 8a into chamber Gand through pipe 9 to the valve l2, When both valves 1l and l2 can be opened, and the air and oil will commingle in spout 14 and be ejected therefrom and ignited and the flame blown through the opening 17 into the forge and against the bridge-Wall and the heat delected to all parts of the forge, andthe products of combustion will escape through the` opening 20, and the air-blast which escapes through perforated pipe 23 will force the products of combustion up behind the screen 24E and protect the operator from the evil effects thereof while inserting or withdrawing articles from the forge.

Various slight changes might be resorted to in the general form and arrangement of the several parts described Without departing from the spirit and scope of my invention, and hence I would have it understood that I do not wish to limit myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall Within the spirit and scope of my invention as claimed.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a forging apparatus, the combination with a hydrocarbon-tank and a casing or furnace supported thereby and'having two openings, of a burner communicating with the oiltank and arranged to project a iiame through one of said openings in the casing or furnace, an air-pipe arranged to discharge air in front of the other opening in the furnace to deflect products of combustion emitted therefrom and means Acommon to said air-discharge pipe and burner for supplying air to both.

2. In a forge, the combination with a casing lined with fire-clay and having an opening in its side wall for the admission of articles to be heated and an opening in its end for the admission of flame, of a bridge-wall disposed in said casin g between said openings, a screen secured to said casing and spaced therefrom in proximity to the opening in the side of the casing and an air-discharge disposed beneath said last-mentioned opening and adapted to force the products of combustion behind the screen,

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
